Abstract (en)
[origin: EP3150673A1] The asphalt composition of the present invention is an asphalt composition comprising 1% to 15% by mass of a block copolymer (a) and an asphalt (c), wherein the block copolymer (a) comprises a specific block copolymer (a-1) and a specific block copolymer (a-2) in specific amounts, wherein the content of a vinyl aromatic monomer unit in the block copolymer (a) is 34% by mass or more and 55% by mass or less, the number average molecular weight of the block copolymer (a-1) is in the range of 20,000 to 73,000, and the number average molecular weight of the block copolymer (a-2) is 1.5 to 5.0 times higher than the number average molecular weight of the block copolymer (a-1).
